“I’ve got a lot of work to do. We won six games,” Mayhew said. “I don’t care where you come from, six games is six games.”

Mayhew met with reporters late Wednesday afternoon to discuss the organization’s progress, but aside from saying linebacker Julian Peterson won’t be back, he didn’t provide much detail about Detroit’s offseason plans. What appears clear is that the Lions no longer need a complete overhaul. Although they didn’t contend for the playoffs, they won four straight games to finish the season despite constant injury problems at quarterback.

“You certainly see a lot less holes,” Mayhew said. “I was very pleased with our finish this year. I thought our coaches did an outstanding job.”

The Lions don’t anticipate any major changes on coach Jim Schwartz’s staff, and Mayhew is looking forward to that continuity. Detroit withstood injuries to quarterback Matthew Stafford and backup Shaun Hill but was able to triple last season’s victory total and put that winless season even further in the past.

All NFL teams are dealing with a decent amount of uncertainty right now because the collective bargaining agreement expires in March, but that doesn’t mean the Lions can’t plan ahead.

Mayhew did announce that Peterson won’t return. He was deactivated for Sunday’s win over Minnesota despite no apparent injury after starting 14 games this season.

Seattle gave Peterson a seven-year contract in 2006 but traded him to the Lions three years later. Mayhew didn’t elaborate on why Peterson is being let go.

“I met with Julian on Monday,” Mayhew said. “I thanked him and told him that we’re not going to bring him back, and we shook hands and we parted ways.”

The Lions are slated to pick 13th in this year’s draft after picking in the top two for three of the last four years. Detroit has used its high picks to add some much-needed young talent, drafting wide receiver Calvin Johnson second overall in 2007, Stafford with the top pick in 2009 and defensive tackle Ndamukong Suh with the second pick last year.

The Lions also took tight end Brandon Pettigrew at the No. 20 spot in 2009 and selected promising running back Jahvid Best at No. 30 last year.

“There will be a great player there at 13,” Mayhew said. “We can go a lot of different places with that pick. … We’re not going to reach for a certain position in the first round.”
